Potentiometer Output Expansion Board
256 Levels of Programmable Resistance Outputs
Potentiometers are available in 10K, 50K, and 100K values
Add potentiometers to any UXP or Existing Potentiometer Board
Add Potentiometer to any UXP Port
This device adds 16 programmable potentiometers in 10K, 50K, or 100K values. Each output has a programmable resolution of 256 steps. The UPOT16 Expansion Module is compatible with any NCD potentiometer as well as any NCD ProXR controller equipped with a UXP port. Expand any NCD ProXR board with a UXP port to include a potentiometer using the UPOT16 Potentiometer Expansion Module! Simply plug the UPOT16 into any NCD Relay board that is equipped with a UXP Port to add potentiometer output to any new or existing system. Please note: this is an expansion module and must be connected to a compatible board to work. This board will NOT work on it's own.Resistance Output
Please keep in mind; our POT series controllers offer a resistance output, and cannot provide a voltage output of any kind without additional electronics. The potentiometers are limited to applications that operate in the 0 to 5V range. Each potentiometer has a maximum current capacity of 1ma. Exceeding these rating will immediately damage the controller.Potentiometers have 3 Connections: A, Wiper, and B. When a low value is sent to the controller, the wiper moves closer to A, decreasing the resistance between A and the wiper (increasing the resistance between the wiper and B). When a high value is sent to the controller, the wiper moves closer to B, decreasing the resistance between the wiper and B (increasing the resistance between the wiper and A). The first 48 channels of wiper values can be set to a power-up default state. It is possible to set the wipers on all outputs individually or simultaneously.
You can send commands to program the output resistance of each individual output, or you program all outputs at the same time. Other commands allow you to set the startup resistance of each output. The ProXR command set allows you to send commands to activate relays, deactivate relays, control all the relays at one time, plus you can send commands that tell a relay to turn on for a few seconds, minutes, or hours. You can assign 16 timers to any of the 256 relays, and set the timers to go off after the duration has expired. The complete command set can be found on page 43 of the ProXR Manual.
ProXR Command Set
If you are new to our products, we would like to introduce to you is a term we call "ProXR". ProXR refers to a set of standardized commands used for computer control and data collection. A controller that supports the ProXR command set is a controller that is built to control up to 256 relays, using commands that can be sent to any controller that offers ProXR compatibility. This allows software developers to create programs for our products, then upgrade or change connectivity options without having to rewrite their software.NCD Component Library
Fully functioning programs for Potentiometers are included with the NCD Component Library. With the NCD Component Library we've "started" the programming for you. We say started because these are fully functioning samples but we've also included the source code so you can customize them to your exact needs. The NCD Component Library is a plug-in for the Visual Studio 2005/2008 that greatly simplifies the communications to the NCD product line. The samples can be run in Visual Studio and fully customizable to your needs. Two different Potentiometer samples are available. One for simple control of 8 digital potentiometers and one for storing and reading stored potentiometer values. Start by downloading the FREE NCD Component Library from the NCD Component Library Page and you will be communicating with any NCD device faster that ever!
 The above sample demonstrates simple control of 8 digital potentiometers. Compatible with all ProXR POT Series Controllers. |
